AIDS is caused by a virus called HIV, the Human Immunodeficiency Virus. If you get infected with HIV, your body will try to fight the infection. It will make "antibodies", special molecules that are supposed to fight HIV.
When you get a blood test for HIV, the test looks for these antibodies. If you have them in your blood, it means that you have HIV infection. People who have the HIV antibodies are called "HIV-Positive".
You don't actually "get" AIDS. You might get infected with HIV, and later you might develop AIDS.
You can get infected with HIV from anyone who's infected, even if they don't look sick, and even if they haven't tested HIV-positive yet. The blood, vaginal fluid, semen, and breast milk of people infected with HIV has enough of the virus in it to infect other people. Most people get the HIV virus by:
• Having sex with an infected person.
• Sharing a needle (shooting drugs) with someone who's infected
• Being born when the mother is infected, or drinking the breast milk of an infected woman.
Getting a transfusion of infected blood used to be a way people got AIDS, but now the blood supply is screened very carefully and the risk is extremely low.
There are no documented cases of HIV being transmitted by tears or saliva, but it is possible to be infected with HIV through oral sex or in rare cases through deep kissing, especially if you have open sores in your mouth or bleeding gums.
There is no cure for AIDS. There are drugs that can slow down the HIV virus, and slow down the damage to your immune system. But there is no way to get all the HIV out of your body.
There are other drugs that you can take to prevent or to treat opportunistic infections (OIs). In most cases, these drugs work very well. The newer, stronger anti-HIV drugs have also helped reduce the rates of most OIs. A few OIs, however, are still very difficult to treat
By the end of 2003, there were 37.8 million people living with HIV/AIDS, including 17 million women and 2.1 million children under the age of 15. AIDS is a serious matter and has to be dealt with seriously.參考資料： AIDS fact sheet and me

The City Where I live
I live in Taipei, the largest city in Taiwan with a population of about three million. I consider it the most beautiful city in the world.
There are many tall buildings, stores as well as numerous cars and motorcycles. We can buy almost everything we like here. Children can get a good education and adults can find good jobs. In short, Taipei is a prosperous city.
Although Taipei s not perfect, I love her and I will do my best to make her more beautiful and peaceful.
My Time of Happiness Each Day
As a student, most of my time is spent on school work and other school-related activities. Consequently, my time of happiness each day is very limited.
However, this is not say that I am not happy every day. In fact, I really enjoy coming home from school each evening and having dinner with my family. After dinner, I watch some T.V. with my family. This is a happy time for me every day.
But my happiest time of a day is just before I fall asleep. Lying in bed, I think about all I achieved that day, and it makes me happy to know that the day was worth living.
